Fire Dept. Called to Donda West’s Home & She WAS WARNED TO NOT HAVE SURGERY

We're told that at 7:35 PM Saturday night, paramedics responded to a 911 call and transported West to nearby Centinela Freeman Hospital in Marina del Rey. We're told it was a "sick person call."

A hospital spokesperson tells TMZ that an unresponsive West was brought to their ER around 8:00 PM Saturday night. They attempted to resuscitate her, but were unsuccessful. She was pronounced dead around 8:30 PM that night.

TMZ has learned that just weeks before Donda West died, a plastic surgeon refused to perform procedures on her because of a health condition that could have led to a heart attack.

We've learned Beverly Hills physician, Dr. Andre Aboolian, was set to perform a tummy tuck and breast reduction on Ms. West, but told her she needed to get clearance from an internist whom Dr. Aboolian recommended. We're told West never went to that doctor, and subsequently had the procedures performed — but not by Dr. Aboolian.
